I know my reading comprehension on this thread hasn't been very good,
but I'm going to try again.

pfctl -k did kill a state, but it appears that a reply packet from
195.14.50.21 recreated a state entry, probably just bad timing.  You
should try killing the state again, perhaps with

    pfctl -k 195.14.50.21 -k 78.107.71.38

And maybe before that, add an extra block rule in the opposite direction
to block replies, at least temporarily just to stop these state entries
from being recreated.
